Report Abuse. The collision of an oceanic plate, and a continental plate produce a plate boundary known as a subduction zone. The colder, denser [typically basaltic crust (approx. 3.3g/cm^3)] oceanic plate is forced underneath the less dense [typically granitic (d= 2.7)] continental crust.
collide, the density of the plates determines which one comes out on top. Oceanic crust is more dense than continental crust. When two plates carrying oceanic crust meet at a trench, the plate that is. less dense dives under the other plate and returns to the mantle.
